The Newick Utilities are a set of command-line tools for processing phylogenetic trees. They can process arbitrarily large amounts of data and do not require user interaction, which makes them suitable for automating phylogeny processing tasks.

The Phylogenetic Tree server creates a distance or parsimony tree from a set of input sequences. It includes functionality for drawing the tree in several forms (radial, unrooted, rooted, phylogram or cladogram) with various other options.
